Root growth of Arabidopsis SiMYB75 over-expressing lines (#L1, #L2 and #L3) and wild type (Col-0) seedlings under various abiotic stress treatments. (a) Phenotypes of the transgenic and Col-0 plants under normal Murashige and Skoog (MS) medium and MS medium supplemented with 150 mM mannitol, 150 mM sodium chloride (NaCl) and 10 µM abscisic acid (ABA); (b) Root length was recorded after 10 days. For each experiment, 16 seedlings/lines were used. Data represent means ± SD from one experiment and the experiment was repeated once more and similar results were obtained. Different letters above bar mean significant difference between each transgenic line and Col-0 at P ≤ 0.05.
